Question
Write a Java program that does the following:
1. Creates a string array called firstNames that holds these values "John", "Frank", "Nick", "Amanda", "Brittany", "Amy", "Deborah", and "Stirling".
2. Creates another string array called lastNames that holds these values "Thompson", "Smith", "Jones", "Keribarian", "Lu", "Banafsheh", "Spielberg", "Jordan", "Castle" and "Simpson".
3. Now add a method that creates an array list called randomNames which picks a random first name from the array in step 1 and a random last name in the array from step 2 and creates a new string containing the first name followed by a space " " followed by the last name (for example "John Lu") and adds it to the array list called randomNames. Do this 50 times.
For 10 extra credit points, make sure the array list randomNames has only unique names, no duplicate names (hint: look at the set data structure in Java, there are other ways to do this as well).

Explanation / Answer
StringArrayTest.java
import java.util.ArrayList;
import java.util.Random;
public class StringArrayTest {
public static void main(String[] args) {
String firstNames[] ={"John", "Frank", "Nick", "Amanda", "Brittany", "Amy", "Deborah", "Stirling"};
String lastNames[] = {"Thompson", "Smith", "Jones", "Keribarian", "Lu", "Banafsheh", "Spielberg", "Jordan", "Castle","Simpson"};
System.out.println("Random Names List: ");
System.out.println(generateNames(firstNames, lastNames));
}
public static ArrayList<String> generateNames(String firstNames[], String lastNames[]) {
ArrayList<String> randomNames = new ArrayList<String>();
Random r = new Random();
for(int i=0;i<50;i++) {
String s = firstNames[r.nextInt(firstNames.length)]+" "+lastNames[r.nextInt(lastNames.length)];
if(randomNames.contains(s)) {
i--;
} else {
randomNames.add(s);
}
}
return randomNames;
}
}
Output:
Random Names List:
[Nick Simpson, Deborah Smith, Deborah Simpson, Brittany Simpson, John Jones, Amy Jones, Amy Keribarian, Stirling Keribarian, John Spielberg, Stirling Castle, Frank Spielberg, Deborah Jordan, Deborah Lu, John Banafsheh, Frank Lu, Frank Jordan, Amanda Spielberg, Brittany Castle, Deborah Jones, Amy Spielberg, Nick Thompson, John Lu, Stirling Thompson, John Thompson, Amanda Keribarian, Frank Jones, Stirling Banafsheh, Amy Smith, Amy Simpson, Brittany Jordan, Amanda Jones, Frank Keribarian, Nick Jordan, Amy Lu, Nick Jones, Stirling Spielberg, Deborah Banafsheh, Amanda Jordan, Stirling Lu, John Keribarian, Frank Castle, Frank Smith, Frank Thompson, John Jordan, Frank Banafsheh, Stirling Simpson, Deborah Spielberg, Amy Jordan, Amanda Thompson, Brittany Banafsheh]
